Research 101: a.k.a. Learning to Kill (on paper!) by Allison Brennan

Jenn McKinlay: Last week I had the very good fortune to sign books at the Poisoned Pen Bookstore with the extremely talented Allison Brennan. Of course, I asked her to visit us and she very graciously agreed. So here she is to talk about the warm and fuzzy topic of writing what we know or rather what we don't know.

BUY NOW!

Allison Brennan: Later this year, Im presenting a workshop titled How Can I Write What I Know When I Havent Killed a Man?

Its a fair question. Especially when writers are constantly told: Write what you know.”

Well, if I only wrote what I knew? My books would be mind-numbingly dull. Im a mom. A daughter. A wife. You know—like millions of women. I once worked in the California State Legislature, which sounds more exciting than it was. (Spoiler: it wasnt.) I went to a college prep high school, dropped out of college after two years, and my first job was at a bookstore, where I had to prove I could alphabetize and make change. I've also been a bartender, admin, hostess, a waitress for roughly two minutes (I was terrible), and spent a summer at Marine World learning how carnival games work—yet still couldnt win a single one.

 The truth is: if you're writing crime, thrillers, or suspense, you cannot rely on television for research. Just because a fictional FBI agent tracks a suspect cross-country doesnt mean the real FBI lets agents hopscotch around the country like Jason Bourne on a road trip. (Yes, I made that mistake once.)

 Some authors do write from specialized experience—doctors writing about doctors, veterans writing military thrillers. It adds a layer of authenticity thats hard to fake. Tess Gerritsen made Maura Isles come alive with her medical background. John Grisham nails courtroom drama. Tom Clancy practically was a submarine. And Jack Carr? Real-deal Navy SEAL turned bestselling author.

 But heres the thing: Tess had never been a cop, and she still gave us Jane Rizzoli. Lisa Gardner has never been a man, but writes in the male POV quite well. And Im reasonably certain Gregg Hurwitz has never moonlighted as a government assassin. (But if he has...I take it back. Great job. Very convincing.)

 So no, Ive never killed a man. But I have a vivid imagination. And if I can picture it? I can write it.

 And I’ve pictured some very fun, er, interesting, um, diabolical … well, let’s just say my husband definitely doesn’t want to get on my bad side,

 Let me introduce you to my best friend: The Book of Poisons. That book has helped me off more characters than I care to count.

 Back when I was writing my second novel—my debut wasnt even published yet—I needed to figure out how to sabotage a car so it would break down after only a few miles of driving. This was before Google answered all of lifes weirdest questions. So I called mechanics in my town.

 Hi, Im Allison Brennan. Im writing a novel. What could I put in a cars gas tank to make it stall a few miles down the road?”

 Shockingly, no one answered my question. Instead, they hung up. I suppose I’m lucky they didn’t call the cops.

 Desperate, I brought it up at my nieces baptism (as one does), and my brother-in-law said, Hey, my buddys a mechanic. Let me grab him.”

 Five minutes later, Im pitching this mechanic my scene, explaining that sugar doesnt quite work unless the gas is low. He nods and says, You want to clog the fuel filter. Thatll do it.”

 We brainstorm. He suggests molasses—heavy, slow, perfect for settling at the bottom of the tank and causing problems right on cue. Boom. Sabotaged car. Kidnapping scene secured.

 Perfect.

 Since then, Ive:

 * Observed an autopsy.

* Played both hostage and bad guy during FBI SWAT training.

* Toured Quantico.

* Done countless ride-alongs.

* Interviewed experts about everything from blood spatter to bomb tech.

 All to make my stories more authentic—even if Im still making stuff up for a living.

 My latest book, Beach Reads and Deadly Deeds, is my 49th novel. Its a little lighter than my usual thrillers (read: fewer corpses, no blood), but the research was still essential—especially since Id never been to the Caribbean.

 In the first draft, I had my characters taking a hot air balloon ride. Very romantic. Except... there are no hot air balloons on Caribbean islands. At all. I researched how they work, and realized theres a very good, very scientific reason theyre not floating around out there. Ive since forgotten what it is—but the balloons had to go.

 Then theres the fictional island of St. Claire, where my protagonist Mia Crawford is sent on a mandatory vacation. I made a rough map to help with continuity. Then midway through the book, I hit a problem: a scene required Mia to hike from point A to point B, but there was no path. I panicked. My entire mountain-trekking sequence was ruined.

 Until I remembered: St. Claire isnt real. I made it up. I can put a path anywhere I want.

 Waterfall too far north? Slide it south. Boom. Problem solved. Magic of fiction.

 Now, I have made mistakes. Some on purpose, for the sake of the story. Others? Honest goofs. Like the nurse who emailed me to say she threw my book across the room because I miscalculated a Valium dose by about... 500%. Whoops.

 The thing is, we dont know what we dont know. Thats why research matters. But I try not to let my research show. It should be invisible. Seamless. If readers are too busy noticing my fun and clever facts, theyre not fully immersed in my story.

 My rule of thumb? Willing suspension of disbelief.

 If the characters are compelling and the story is gripping, readers will go along for the ride—even if a detail is a little off.

 That said… if I were to plan a murder, Id want to do it right.

 I mean, Id want my characters to get away with it. Definitely just my characters. Wink wink. (Ha! Just kidding! In case the NSA or someone is reading this …)

So tell me: Do you appreciate when authors get the research right? And are you willing to overlook a few missteps if the story's too good to put down?

  1. Congratulations, Allison, on your newest book . . . I must admit, the "mandatory vacation" captured my attention!
    Am I willing to overlook a few missteps if the book is too good to put down? Of course [and, to be honest, I probably don't know what those missteps were anyway.] I certainly appreciate when authors get the research right, but when the book is too good to put down, I'm not likely to know about that research . . . I had no clue there were no hot air balloons on Caribbean islands and if your characters went off on a hot air balloon ride, I'd never have known that was a "goof' . . . .

    1. I agree -- I often just go along for the ride. There are some things that irritate me but only because I know a lot about one or two subjects, so then if they don't get it right I roll my eyes. But usually, if the story is good, I don't care :)

  2. Allison, your book sounds terrific. I love that you set it on a brand new island! Is it a part of a series? Please tell us a little more about your main character.

    1. Thank you! Yes, I needed a fictional island because it's privately owned, so I picked the area near St. John so that I didn't have to deal with international jurisdictional issues (since I write crime fiction, even though this is an amateur sleuth, I have to get the cop stuff mostly right!) This is a stand alone -- only the second stand alone I've ever published -- so it won't be a series. Mia Crawford is a hard-working financial planner who is also responsible for the financial security of her grandmother, which makes her doubly responsible. Her only fun is reading books and posting reviews. It's her five year anniversary at work, she's turning 30, and her boss offered her a promotion which, if she takes it, means complete financial security but no outside life. So she is on the island thinking this is her last chance for a fling, for fun ... and she gets embroiled in the mystery of a guest who went missing, then turns up dead.

  3. ALLISON: Congratulations on your new book!
    I am glad you put Mia on an imaginary Caribbean island, so you could have her hike from point A to B. Too sad that Mia couldn't go on a hot air balloon ride. Bad things happening while on vacation sounds fun for the reader!

    Re: research. I do appreciate all the efforts authors make to get the scene right.
    I am not so sure that Gregg H is so innocent in knowing stuff about assassins. Just saying...

    Yeah, asking mechanics about how to sabotage a car would raise some eyebrows, but I am glad your brother-in-law's buddy was able to help you!
    But I understand that mistakes still creep in books. I certainly would not have not known about the Valium goof!
    I am usually willing to suspend belief to keep reading, as long as I am not taken out of the story (stop reading).

    1. Thank you! And yeah, Gregg is someone to keep an eye on ... The valium goof was my fault 100%. I had a Vicodin prescription from my C-section years before. I looked at the bottle and didn't understand that the 5/100 was Vicodin to Tylenol. So 500 mg of valium would be a lot ... not to mention that they are to completely different drugs, LOL.

  4. I didn’t know that they don’t have hot air balloons in the Caribbean and doubt that I would have questioned it. Someone would have and given you an earful I am sure.
    I do appreciate the research and have stopped to look things up that don’t quite ring true. It is annoying to be taken out of the story like that. Sometimes I am right and sometimes I learn something new.
    49 books! Good for you.

  5. Isn't research fun? I love it when the subject matter expert gets into your question instead of hanging up. I've consulted with a bike shop mechanic, a forensic anthropologist, a nurse, a wine bottling plant manager, historical train guys, a midwife, Luci Zahray (the Poison Lady), a prison librarian, and more in the course of writing my books. And yes to the the Book of Poisons, plus A is for Arsenic and Wicked Plants, all at my fingertips!

    Now I want to know why hot air balloons don't work in the Caribbean. Congrats on your new book and on remembering you can change the island you made up.

    1. Oh, I want your arsenic book! Going to amazon after this comment ... Basically, on an island in the Caribbean, it's too windy and unpredictable and it's very hard to find a safe place to land near the coastal area. You need a large, flat area. So if you had a very large island, you could do it, but St. Claire is very small so it definitely wouldn't work.

  6. Welcome Allison and congrats on 49 books! On a different topic, I'm curious about why you chose to write a lighter book this time around?

    Replies
    1. Hi Lucy! Well ... I wanted to write a stand alone, and I was asked to write something more romantic mystery than a thriller because I already have two thriller series. So the only real option was to go a bit lighter in tone, and I also wrote the book in first person -- first book I've ever written in first. (I sometimes have a first person character in my thrillers, but never the whole book!) I'm always trying to grow my audience. I think my core readers loved the books, I just don't know if I gained anyone yet! We'll see :)

    Welcome, Allison! Always so wonderful to see you! And congratulations on your 10 millionth book or whatever it is :-)
    I really appreciate seamless research. I love when I learn something in a novel, especially when that new knowledge seems to effortlessly flow from the story. And there would have been someone reading your book who would have known that! How many times have I read books and at one point stopped in my tracks saying – – that would never work! No one could do that! And it’s obviously just authors convenience.
    And you are so right!
    The realization that what we are writing is fiction – – that’s still always makes me laugh. Yep! We can find a way to make it happen.
    Cannot wait to read this book! Congratulations! And love love love to your daughter.

    1. LOL -- I went through the FBI Citizens Academy in Sacramento. To get into it, I had to be invited by either a graduate or someone in the FBI. I guess I called the office one too many times asking questions, so they invited me. A basic background check was needed and then voila! I was in. It was a 9 week program and after, they invited graduates to be extras in FBI SWAT training at McClellan Air Force Base. I did it 4 or 5 times over the years, it was informative and fun.

  10. This was a fun peek behind the curtain post! I am able (and willing) to suspend belief for the most part. But like the nurse you mentioned who couldn’t get past the medication flub, it can be hard for me to see past things that take me out of the story and I cannot fully believe in the character any longer… I do think research is what separates the good writers from the rest.

    1. Exactly ... everyone is an expert in something, so I try to remember that when I write. There are some things that fall under the guise of "you can't please everyone all the time" because everyone has different experiences. On the same book, I had emails from two different readers the same week -- one said "Oh my God, this would never happen, you don't know how the FBI works!" and the other said, "Wow, I think I know the FBI agent you wrote this about! He would totally do this!" LOL.

  12. Allison, congrats on the new book! I love it when you can't separate the research from the story. And consulting experts is one way to begin--then you walk that line between advancing the story and not overloading all that fun information into your tale. My favorite research story involves a scene in the making of LOTR, when Peter Jackson was instructing Christopher Lee on how to react when he's stabbed in the back. And Christopher Lee politely illustrated (from experience) how someone in that situation would react. Gulp!

  13. ALLISON: Welcome to JRW and congratulations on your new novel BEACH READS. My comment may be long.

    Though I am able and willing to suspend belief for the most part, like the nurse you mentioned, then I would not get past the medication flub.

    When the author puts in the research, this gives me the opportunity to learn something new. When something seems inaccurate to me, i remind myself that the novel is FICTION. Authors often add an Author's Note about an historical fact, for example, and how they changed it for the story.

    My reading changed after my college English classes. The professors always asked what is the message that the author wants the reader to know from reading the novel.

    As a reader of light mystery novels. I read for entertainment, not for homework.

    Since I started writing my own novel, I have to study the books that I enjoyed and it is different. I HAVE to analyze the how, where, which, who and why in the story instead of just enjoying the story.

    1. That valium error was in my 5th book -- SEE NO EVIL. I learned after that to ask my sister in law or cousin, both nurses, when I want to add a medical detail. In fact, my cousin read a scene where my character Lucy performed an emergency C-section on a woman who had been shot and was dying because the paramedic couldn't do it for liability reasons. She corrected a couple of things, and the scene was terrific. When I really don't know and it's not important, I try to be as vague as possible. Less is more! :)

  14. TV shows are the worst offenders (IMHO) when it comes to accuracy. But they probably can only afford so much time and money on research. Many years ago my husband was watching JAG and was surprised they had a Lt Commander wearing the insignia of an Admiral, high ranking officers saluting enlisted staff first, and so many other mistakes. My husband ( who is a retired JAG) wrote to Mr. Bellisario (the director) and was invited to the set to talk things over. Very fun outcome

  15. Diana "Authors often add an Acknowledgement about an historical fact, for example, and how they changed it for the story"
    I like when authors do this and provide other interesting comments in their acknowledgements. Author's Note and Acknowledgements are pages I read first. I find them so helpful and interesting and it gives the reader a peek into the authors life, family, their research and other fascinating facts.

  16. Love this. Allison, your books have captivated (and held me captive) for many years. Congratulations on your latest.

    As for your question, depends. I'm willing to suspend belief and wink on small and obscure matters, I'm not quite so generous on the easily ascertained bits or impossible premises. Then again, truth is stranger than fiction.

    1. Thank you so much! ... And yes, easy facts that are wrong frustrate me (sometimes they are honest mistakes ... like just a typo that isn't caught but changes the meaning of something. I've done that once or twice and I hate that I miss it.) ... Truth is definitely stranger than fiction. My book The Missing Witness dealt with a conspiracy among non profits to profit off the homeless crisis in Los Angeles, where one of the conspirators was an elected official. Literally the month my book came out an official was indicted for profiting off the homeless (I think she funneled money to her sister's non-profit. Very close to my story!)

  17. As those before me have said, I really appreciate good research, but mostly when it is invisible to me. I have occasionally read books where the author fell so in love with his/her research that every single thing he/she learned seemed to get dumped into the novel. Not cool.

    Small errors are unlikely to bother me, unless they draw my attention away from the world of the story. The wrong Valium dose probably wouldn't have done that for me, as I'm not trained in medicine, but I can see how it did for the nurse. Even then, I'm unlikely to get too worked up about one mistake.

    I would say that I hold authors to a higher standard of getting things right than I do TV writers. I just assume TV writers are under pressure to crank out scripts fast, and there is a much lower bar of expected accuracy.

  18. Hello Allison. I don't think I'm bothered by little things being off but big things, like medicine doses, might bother me especially if I know it is really off. I live in northern California, and I would notice if you had someone attending a concert at Burbank's house. Luther Burbank Center has concerts, but Burbank's house is a small, historical garden next to the cottage his widow lived in. They are miles apart. I might be able to look past it, I might not. I guess it depends on the book.

    I do understand having to take vacation due to having accrued too much paid-time-off. I've been to take some time off because I've got too many hours accrued, but I've never been sent anywhere, just told to take time off.

  19. Congrats on the new book, Allison -- it sounds like great fun. I laughed out loud when you said you couldn't figure out how to get Mia across the island b/c there was no path until you realized you made it up -- you could add one!

  20. Thanks for telling us about your research, Allison. I enjoy interviewing people with interesting jobs to get the facts right in my Linder and Donatelli series. However, I once located Bern's main department store, well-known to everyone in the city, on the wrong street. American readers probably wouldn't know that, but my Swiss readers certainly did--and I felt like an idiot, since I walk or ride the tram past that store several times a week. Oh, well. Everyone makes mistakes. Which is why I try to be tolerant when I catch a mistake in a book.

    I imagine ballooning in the Caribbean is limited by the lack of wide open spaces to safely land. You’d go up, the wind would catch you, and pretty soon you’d be over the ocean.

    My husband is an aerospace engineer, so it’s hard for him to watch or read anything in that field because there are almost always errors. I’m more forgiving, and don’t get mad anymore when people say cement when they mean concrete.

    It did bug me in a recent book reading about “the PCH.” It’s “the Pacific Coast Highway” but just PCH.

    1. You're right -- no place to land on small islands, and also there's a wind issue. I'm in Phoenix and we have LOTS of hot air balloons, but it's seasonal -- and they land in this HUGE desert area near me off highway 17.

  25. Research is such a fascinating and far-reaching creature. I enjoy that peek at what you do to make your novels accurate (or not). I read James Rollins' novels and one of the things I like is that he includes a "Fact or Fiction" section at the end of his thrillers. It can be scary the number of things I thought were fiction were indeed fact. A bit of education after entertainment. Also, I don't know how innocent Hurwitz is, but he definitely takes his vodka research seriously! -- Victoria
